The San Antonio Spurs signed first-round pick George Hill on Tuesday, Hill's agent said.

The Spurs took Hill with the 26th selection, but didn't have to sign him. Michael Whitaker said Hill participated in summer league with the Spurs and had been working out in San Antonio since Aug. 18, despite the fact that he hadn't officially signed.

"The Spurs are a championship organization," Whitaker said. "They told us all along they wanted to get the deal done, they just wanted to use the time to sign free agents. We just took them at their word."
